  • the present invention relates to a method for producing a cushion spring, in particular for upholstered furniture or mattresses, a cushion spring, a mattress and upholstered furniture.
  • DE 10 2013 103 644 discloses a spring made of wire of a spring core, which can be used for example for mattresses or upholstered furniture.
  • the spring consists of a helically wound spring steel wire, which deforms under load.
  • Such springs have been proven in the manufacture of upholstered furniture and mattresses, with the springs being heat treated during manufacture to make them more tough. By such a heat treatment is a lowering of individual springs and consequent lowering, such as cooling in upholstery or mattresses, prevented.
  • the method for producing a cushion spring at least partially, a heat-sensitive color indicator is applied to a spring steel wire before, during or after bending the spring steel wire, and then the spring steel wire is heated to at least the Umzzi temperature of the color indicator before the pad spring is completed.
  • the heat-sensitive color indicator ensures that the heat treatment of the spring steel wire can be made visually visible.
  • the spring steel wire is heated above 280 ° C in the heat treatment.
  • the spring steel wire for example, be heated to a temperature between 290 ° C to 310 ° C, the duration of the heat treatment can be designed depending on the spring steel wire used, but at least briefly the temperature above 290 ° C must be achieved.
  • the turnover temperature of the color indicator is therefore preferably also at least 250 ° C, in particular between 290 ° C and 31 0 ° C. At these temperatures, the positive effects of the heat treatment occur.
  • the color indicator can be applied by immersion.
  • the coating can be carried out purely electrochemically or galvanically by applying a voltage.
  • the color indicator preferably has a thickness of between 0.05 to 1 ⁇ , in particular 0.1 to 0.80 ⁇ , so that the color indicator is applied only in small quantities on the spring steel wire.
  • a copper-containing coating is applied as the color indicator, which does not adversely affect the mechanical properties of the cushion spring.
  • the copper-containing coating can also consist essentially entirely of copper, which is applied to the spring steel wire with a small layer thickness. It is also possible to use suitable copper alloys to set a certain turnover temperature. In the color change then the copper-colored coating is darker or lighter, depending on the temperature reached, which is visually easily recognizable.
  • the color indicator is only partially applied to the spring steel wire, which is particularly material-saving.
  • the color indicator can be applied, for example, only on a central region of the cushion spring, which deforms under load, so that at least visible by the color indicator, whether the deforming region is heat treated. Then arranged on opposite sides end rings of a cushion spring can remain uncoated. Of course, it is also possible to completely coat the cushion spring with the color indicator.
  • a cushion spring is provided, which is used in particular in a mattress or upholstered furniture.
  • a viewing window is provided so that an end customer can recognize whether the pad spring has been heat treated accordingly.
  • FIG. 1 shows a photographic view of a cushion spring with a coating according to the invention of a color indicator, before and after the heat treatment, and
  • Figure 2 is a conventional pad spring without color indicator.
  • FIG. 2 shows a cushion spring without a coating of a heat-sensitive color indicator. It can be seen that the spring steel wire from which the cushion spring is made has the same color everywhere and is not visually recognizable as to whether a heat treatment has been performed on this cushion spring to make the spring steel wire toughened.
  • a cushion spring according to the present invention is shown on the left side in Figure 1, a cushion spring according to the present invention is shown. The cushion spring is helically wound in a central region between two parallel end rings and coated in this central region with a heat-sensitive color indicator. As can be seen, the central area has a different color than the two uncoated end rings of the cushion spring. The middle area is much darker due to the color change of the heat-sensitive color indicator due to heat treatment.
  • On the right side is a padded spring with color indicator and without heat treatment.
  • the color is uniform.
  • a copper-containing coating in a thickness of between 0.1 ⁇ m to 0.75 ⁇ m was electrochemically applied to the wire in the middle region.
  • the wire was passed through a dip bath while a voltage applied to the spring steel wire, so that the copper-containing coating has settled on the surface. This method makes it possible to set the layer thickness and the coated areas comparatively accurately.
  • the color indicator can be applied to the still undeformed spring steel wire, so that it only after the coating in the form of a Pad spring is deformed. Preferably, then a complete coating is made. But it is also possible to first form the spring steel wire to a cushion spring and at least partially coat the already formed spring steel wire.
  • the bent spring steel wire was subjected to a heat treatment, whereby the bent spring steel wire was heated to a temperature between 210 ° C to 250 ° C. By heating to this temperature, the color indicator was activated, so that an optically detectable color change was made in the central area.
  • the cushion spring can be bent to different types of springs.
  • the cushion spring may be formed as a Bonellfeder, pocket spring, open coil or another spring type.
  • the upholstery springs can also be combined into units of several upholstery springs and then processed into mattresses or upholstered furniture.
  • At least one transparent window or windows formed by a recess can be provided in the cover, so that a visual check is possible as to whether the upholstery spring is heat-treated.

Abstract

L'invention concerne un procédé de fabrication d'un ressort d'ameublement, en particulier pour meubles rembourrés ou matelas, ledit procédé comprenant les étapes suivantes : appliquer au moins par endroits un indicateur de couleur thermosensible sur un fil d'acier à ressorts, pendant ou après le cintrage du fil d'acier à ressorts, chauffer le fil d'acier à ressorts pour le porter à au moins la température de virage de l'indicateur de couleur et finir le ressort de virage. L'invention concerne en outre un ressort d'ameublement selon l'invention, un matelas et un meuble rembourré dotés d'un tel ressort d'ameublement.
